hi Sidhabhi. thanks for reply. this is a screenshot of wifi calling in action from Airtel tamil Nadu circle, android 10, one plus 7 pro. we have verified that wifi calling works as expected. now I used his sim card in my S8 when i took above screenshots in the original post. i dont know what could be the issue now.
Yeah..they were testing it in Tamil nadu. Hyderabad and in some parts of UP..that's why I asked you..have word with your network operator..because in my S10+, its available but not working..
